SEAL ATTACHMENT FOR LOCKS.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed March 13, 1909. Serial No. 483,137.

To all whom it may concern.'

Be it known that I, CHARLES H. JOHNSON, a citizen of the United States,and a resident of Petaluma, in the county of Sonoma and State ofCalifornia, have invented a new and Improved Seal Attachment for Locks,of which the following is a. full, clear, and exact description.

This invention relates to seal attachments for locks, especially thoselocks used on suitcases, trunks, boXes for legal papers, jewel boxes andthe like.

The object of this invention is to provide a device whereby a seal maybe placed over the lock and the same covered up and protected, so thatthe lock itself cannot be unlocked without breaking the seal.

The invention further consists of the construction and combination ofparts to be more fully described hereinafter and particularly pointedout in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specilication, in which like reference characters denotecorresponding parts in all the views, and in which Figure 1 is a sideview of the device, showing the seal attachment on the plate of a lock;Fig. 2 is an enlarged section on the line 2 2 of Fig. l; Fig. 3 is aview of the back of the plate of a lock, showing the means of fasteningand locking the seal attachment to the lock-plate; Fig. l is an enlargedsection on the line 4 1 of Fig. 1; and Fig. 5 is an enlarged section onthe line 5 5 of Fig. 3, showing the means of locking the seal attachmentto the lock-plate.

Referring more particularly to the separate parts of the device, 1indicates a lock of any usual construction; 2 represents a coverplatepivot-ally secured to the plate of the lock by a concealed hinge 3. Thishinge 3 is of such a form and so located behind the plate of the lockthat it cannot be picked from the outside. The cover-plate 2 has akey-hole opening 5 therein, through which a key may be inserted into thekey-hole opening` 6 in the plate of the lock. The opening 5 in the cover2 is adapted to be closed by means of a protector 7. This protector isof any suitable form, but prefer'- ably is hinged to the cover 2 at oneend by means of a pin 8, and is turned up at the other end slightly, asshown at 9 in Fig. 4. This turned-up end 9 permits it to be easilycaught hold of to revolve it about its pivot 8.

Just above the turned-up portion 9 on the `protector 7, is anindentation 10 on its under The pins 8, 11 and 12 pass through the cover2 and have sharpened points 13 which are adapted to pierce through aseal 14e placed between the cover and the lock. These points 13 afterpassing through the seal 14 engage in recesses in the front of thelockplate, as at l5. Thus, these pins serve the double function offorming supports and locks for the protector 7 and for holding the sealin place. This seal 14 may be of any suitable material, such as wax orpaper, and is adapted to be placed between the cover and the lock properso as to protect the latch or key-hole in said lock.

The cover 2 has a latch 16 (see Fig. 5), which passes through an openingin the seal and lock and is adapted to be engaged by a locking-member 17pivotally secured at 18 to the inner surface of the lock-plate. Thelocking-member 17 has a downwardlyextending portion 19 which engages thelatch 1G and prevents it from being withdrawn. This locking-member 17 isalso slidingly held by a pin 2O fastened into the lock-plate, whichengages a slot 2l in the locking-member. A spring 22, suitably securedto the lock-plate, engages the lockingmember 17 and holds it in such aposition that it will automaticallyengage the latch 1G.

At the top of the key-hole opening 6 in the lock-plate is a collar 23which prevents the locking-member 17 from being lifted oil' the latch 16by the means of a wire.

In the operation of the device, the box or other receptacle isfirstlocked, then the key removed and a seal of any suitable form placedover the opening. Then the cover 2 is closed and the pin-points 13pierce the seal and hold it in place, and the cover is automaticallylocked in its closed position, as

shown in full lines in Fig. 2. In order to open the lock, or even to getat the seal, the lock itself must be first unlocked, and this can onlybe done by breaking through the seal. The cover-plate 2 is made with avery slight bevel on its inner surface, to permit room for the seal andat the same time fit closely to the surface of the lock-plate.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
